>>84322492>If you fantasize about something, it's generally because you wish you could do it.That's only partly true, because often, the fantasy is not just the act but how the whole thing plays out.
There are many fetishes which are technically, physically possible in reality, but by the nature of the act changed from how one might imagine it. I've got a fetish for cervical penetration, but while the act itself is indeed possible in reality, it will never play out in the way I fantasized, because in reality it's an excruciatingly painful event with serious health risks.
Similarly, I'm a fan of loli, but rape/coercion/bad-end shit is a turn-off. In real life, pedophilia is inseparable from those negative aspects, which makes acting on it reprehensible.
But in fiction, all those things only happen if you write them such. In fiction, the limitations of reality don't need to apply, and acts which might not be possible, ethical, or even very pleasurable in real life can instead result in a sensual fantasy.
Ultimately it always comes down to understanding the line between fantasy and reality. As long and someone can do that, their fetishes will never be a problem.
